c# - 需要在变量中显示连接信息

Question

我有连接字符串

SqlConnection con = new SqlConnection();

其中 con 包含来自 DLL 或 app.config 的连接字符串信息。

现在我想在不同的变量中显示每一件事。

例如:

var connectionString = "Data Source=172.16.0.9;Initial Catalog=whiziblesem;UserID=mppuser;Password=mppuser";

预期输出:

        a = server name
        b = Database name
        c = username
        d = password

Answer 1

使用SqlConnectionStringBuilder类:

var builder = new SqlConnectionStringBuilder(connectionString);

用法:

Console.WriteLine("Data Source: {0}", builder.DataSource);
Console.WriteLine("Initial Catalog: {0}", builder.InitialCatalog);
Console.WriteLine("User ID: {0}", builder.UserID);
Console.WriteLine("Password: {0}", builder.Password);
